We' make the fifrontyor working, part of the machine, B, Figs, 1, and 2, of cast iron, or anyother suitable material, of a circular disk, with twocircular ribs, or projections, G, and D, on itsl face, to sustain the die stocks, E, F, G, asshown in Fig; 1. We attach the front part, B,to the'front end of a hollow ,ljcylindrical shaft, I, onwhich shaft we fit pulley, Kl' This shaft revolves in bearings, as ,sho-wnat L, Fig.1, and at L, and FL, Fig. We make the die stock E, F, H, offcast iron, or any othersuitable material, of a perfectlcircle in their cross section, and let themintothe circular profjections,uC, and1D,vabout onehalf of their diameters, so that they may be readily turned to adjust the lanes of the rotations ofthe dies to any desired angle with the hollowshaft, I,andj we graduate the outer Yiends,}as shown ate, and a, Fig. 1', so that they may each be set at thesame angle with perfect accuracy, by the assistancef of the 1 guides,orpoints,[d',*and a, &c.

so thatthey may receive the. square shanks ;of the dieholders, as shown at b, and b, Fig. 2, and, also, theladjusting screws, 0, 0, 0, 0,

by which we adjustthe dies tothe size of thetube tobe ornamented. We securethese diel stocks firmly intheir proper position;

(when adjusted as above described,)- by binding screws on the inner parts of the bands, orQsocketsQM, M, &c., as shown at d, d, FigFQLLWe make the dies, 6,0, 6, e, of cast steel or any other suitable material,

or different designs on each, and use any.

number ofdies,'and die stocks, which may be found convenient in any case, (the die stocks always radiating from the center.) We attach the dies to the inner ends of the die holders, 6, b, &c. Figs. 2, and 1, by center pins, or arbors, as shown at f, f, f, f, on which the dies revolve to impress the design; thereby essentially avoiding friction in their operation. These pins, or arbors, may be withdrawn, and one, or more, of the dies changed, at pleasuref To use our machine, for impressing the ornaments on the tube, we set the die stocks so as to bring the planes of rotation of the dies to the desired angle with the hollow shaft, (each die being at exactly the same angle,) and adjust the dies, by i the set screws, 0, c, 0, 0, to the size of the tube to be ornamented. We then place the tube on a proper mandrel, and insert the end beor different, devices, in a spiral opposite to the first, that is, crossing the former, the die stocks have only to be set at the reverse angles, and the tube fed through again, the same as before.

The advantages of our improvement consist in the die stocks being adjustable .so as to brin the planes of rotation of the dies to any esired angle with the hollow shaft.

(which controls the direction of the feed.) And in so constructing, and arranging the machine that its revolving motion will feed the tube, after it has been entered, in the exact proportion as it is wanted, as the revolving motion controls the feed by the an gle of the dies, so that the tube can never be strained, or forced out of shape, for no force acts upon the tube except the pressure of the dies in the direction of its cross section, so that the tube will come from the machine in the desired shape, with all the ornaments perfectly impressed on its surface, ready for use. And in the simplicity, and small expense, of its construction, and use, as the same parts, (except the dies,) are used, for all kinds of ornaments.

We are aware that a series of stationary dies have been long used to ornament tubes ;-and that revolving dies have been used for ornamenting articles while in a vers are not new; we, therefore do not claim any of the parts, as such, as our inventlon, but,

What we clalm as our invention, and desire to secure by Letters Patent, is

, The combination of the adjustable die stocks, (E, F, G, 1-1,) with the revolving dies, (6, e, e, 6,) in a self feeding machine for ornamenting tubes, &c., when the Whole is constructed, arranged, combined, and made to operate, substantlally, as herein described. V
